How to handle Dropzone.js file uploads, then process the form inputs in Express/Node.js

Dropzone.js looks pretty awesome. I have Node/Express configured so that my route is getting the file uploads and the details for them, but what is the right way to handle multiple file uploads and the form data?

If I want the user to upload, lets say, 2+ images and also fill out the form, then click submit, how do I handle the file uploads and form separately?

Right now, when any of the files upload, it submits the form. Should I have two separate forms and routes so that each file upload returns a URL or upload ID that I then dynamically insert into the other form? What is the best practice?
